Comparative Study
Comparison of clinical features and outcomes of hospitalized adult patients with novel influenza A (H1N1) pneumonia and other pneumonia.
A novel swine-origin influenza A (H1N1) virus caused worldwide outbreaks starting in April 2009. The aim of this study was to evaluate the clinical characteristics and outcomes of pandemic 2009 H1N1 pneumonia by comparing to community-acquired pneumonia (CAP) of other origin. ⋯ This study shows that clinical characteristics and outcomes of 2009 H1N1 pneumonia are comparable to those of CAP of other origin. However, some characteristics, including younger age, nonspecific symptoms (including headache, leukopenia, and fatigue), lymphopenia, lower initial CRP and PSI score, and radiologic findings (including bilateral abnormalities and ground glass opacities), may help clinicians to diagnostically differentiate between H1N1 pneumonia and CAP of other origin before the result of RT-PCR are obtained.

The terrorist attacks of September 11, 2001, initiated a shift toward a comprehensive, or "all-hazards," framework of emergency preparedness in the United States. Since then, the threat of H5N1 avian influenza, the severe acute respiratory syndrome epidemic, and the 2009 H1N1 influenza pandemic have underscored the importance of considering infectious events within such a framework. Pediatric emergency departments (EDs) were disproportionately burdened by the 2009 H1N1 influenza pandemic and therefore serve as a robust context for evaluation of pandemic preparedness. The objective of this study was to explore pediatric ED leaders' experiences with preparedness, response, and postincident actions related to the H1N1 pandemic to inform future pandemic and all-hazards planning and policy for EDs. ⋯ Despite a decade of investment in hospital preparedness, gaps in pediatric ED pandemic preparedness remain. This work suggests that raising awareness of pandemic planning standards and promoting strategies to overcome barriers to their adoption could enhance ED and hospital preparedness. Helping hospitals better prepare for pandemic events may lead to strengthened all-hazards preparedness.

Comparative Study
Reducing blood culture contamination in the emergency department: an interrupted time series quality improvement study.
Blood culture contamination is a common problem in the emergency department (ED) that leads to unnecessary patient morbidity and health care costs. The study objective was to develop and evaluate the effectiveness of a quality improvement (QI) intervention for reducing blood culture contamination in an ED. ⋯ A QI assessment of ED blood culture contamination led to development of a targeted intervention to convert the process of blood culture collection from a clean to a fully sterile procedure. Implementation of this intervention led to an immediate and sustained reduction of contamination in an ED with a high baseline contamination rate.

Comparative Study
Emergency research: using exception from informed consent, evaluation of community consultations.
In 1996, the U.S. Food and Drug Administration approved regulations authorizing an exception from informed consent (EFIC) for research conducted in emergency settings when obtaining prospective informed consent is not possible due to the potential subject's critical illness or injury. The regulations require that investigators conduct community consultation (CC) efforts before initiating a study and require that institutional review boards review the results of CC prior to approving a study. However, little is known about how communities view EFIC research or the CC process. ⋯ Overall, members of these two communities expressed satisfaction with the CC session and had relatively high levels of support for the study and trust in physician-investigators.
